What causes tooth wear?


Preston Dental Saskatoon Dental Clinic Services

Tooth wear is not normal. Three causes for tooth wear have been identified:

Acid erosion which appears as grooving or dishing of the biting surface of your teeth. The risk factors for acid erosion are:

  • Chronic dry mouth.
  • Chronic vomiting or “GERD” (Gastroesophageal Reflux Disease).
  • Diet – sports drinks, soft drinks, candies, citrus fruits.
  • Environment – certain acidic work places, swimming pools.

Bite wear which appears as shortening or thinning of your teeth. The risk factors for bite wear are:

  • An unbalanced bite – your teeth should contact evenly on both sides.
  • Grinding your teeth.
  • An overly abrasive diet.

Tooth cleaning abrasion which appears as notching near the gum line of your teeth. The risk factors for tooth cleaning abrasion are:

  • Abrasive dental home care aids such as some toothpastes and toothbrushes.
  • Using too much pressure on your toothbrush or toothpicks when cleaning your teeth.
